Your application paperwork

The Solar Massachusetts Renewable Target (SMART) program pays homeowners a set incentive for the solar energy their system produces, with enhanced rates for low-income households. It is run by the state Department of Energy Resources for customers of Eversource, National Grid, and Unitil, and a program administrator (CLEAResult) reviews applications. Your solar installer normally submits the SMART application as part of your project.

Steps to apply

  1. Confirm you are a customer of Eversource, National Grid, or Unitil and choose a solar installer.
  2. Have the installer design the system and confirm available SMART block capacity in your utility territory.
  3. The installer submits the SMART application to the program administrator (CLEAResult) for review and DOER approval.
  4. After interconnection and approval, you receive the SMART incentive payments tied to your system's production.
